I have a new Swiffer 360 duster that i use occasionally to just dust around my room. It of course picks up all the dust and when im done, I just step outside and shake it like a crazy man to try to get all the dust off. Is that all i have to do to clean it? Because I feel uncomfortable using it on my keyboard and precious stuff after I have wiped super dusty countertops in the past. Is shaking it all I need to do? I dont want to have to do anything like but it in some special cleaning solution haha, just simple methods.
